For a few days I receive an 403 error when I try to use one of the Tahoma devices in the Homey app When I remove the somfy tahoma application and reinstall it, it works again for a few hours but later the error returns. Does anyone have an idee?? I use the Homey app and have Homey premium without a homey pro hub. ![1000050814](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/9/99e1338aeff2e78b8641e53c6c5223c9026a4423.jpeg) ---

403 means “forbidden”. It might have to do with rate limiting \> allowing only a certain amount of commands in a certain timeframe. I think it’s best to inform the app developer, by moving your issue to the Tahoma app topic, as mentioned on the app page at homey.app store ---

But this community is also always very helpful and otherwise it’s just to inform other users.. I couldn’t find anything on Somfy, Tahoma and 403 error. ---

That’s allright as well, but I meant the link to the forum app topic, which is mentioned too at the app store page 😉 I’ve not read about that Tahoma issue either. ---

I had the same issue. Removed the somfy app and tried to login again on the app in the homey interface. Now i get error 401 and now i cant use the somfy products via the Homey app ---

Thanks @Peter_Kawa for picking this up as I hadn’t spotted it. I’m not sure if the error 401 is related to the same issue as the 403 error as that generally indicates the credentials have been entered incorrectly, but maybe it is the same issue identifying in a different way. ---

Yesterday I could finally reconnect the app and devices. It worked that evening. To bad, today I receive again the 403 error 👎 ---

I have the same errors with Somfy in the Homey app. For a few weeks now. Tried all the usual troubleshooting but the errors keeps coming back. ---

Yes me too. I removed the application but then could sign on again. The i got the 401 error. For now i just wait and be patience. When a solution isn’t live soon I’ll remove the Homey app and quit my paid subscription. ---

Well, Jack, there’s a secret option here: you can `ask` what’s going on, instead of sit and wait? FWIN Somfy is the issue, not Homey. You’ll find the link to the Somfy Tahoma app topic on the app page @ homey.app store. There’s the issue explained, and has the explanation you were looking for. Just FYI > [@Jack\_Vogelaar](#): > > I will end mij Homey subscription Pointless to say, this is just a user forum. ---

So there is already a notification about this problem in this topic with 2522 posts. And reading the post from Adrian Rockall it seems to me it’s due to Homey Cloud using the same IP address for many Homey Cloud users. The post is from 7 october and appearantly since the apps from Somfy TaHoma and Connexoon were automatically updated to version 4.0.122 somewhere early october. Reading the last post i conclude thatHomey has not been able to solve the problem yet. I see no harm in creating this topic for this 401 and 403 errrors for all (paying) Homey Cloud users to be able to find information about the problem they are suddenly dealing with and i hope this posts helps a little bit and we will soon be informed about the solution to expect. (Or not). ---

Homey won’t respond as I write the app and the issue is caused by Somfy’s security measures, so there’s nothing Athom can do. Somfy are now concentrating on the local API, so they aren’t interested in making any changes. I published a new version a few hours ago to try and solve the problem, but that process will take about 26 hours, assuming it works. ---

Hi all, I’m facing same issues. Just removed Somfy from Homey and reinstalled. I do get the option to enter my credentials, however I receive following: ”blocked for 31232.052000045776s”. I can log in dircetly into the Somfy app however, so the block is not from them. Please let me know if anyone has found a solution / work around.
